Figure 3 (A to D) The video workstation-based User Interface (Navigant, Stereotaxis Inc.) shows four paired Navigant images (upper two, two-dimensional sync C-arm on the left and three-dimensional NaviSphere on the right, which represent navigation of the magnetic catheter to (A) left superior pulmonary vein; (B) left inferior pulmonary vein; (C) right superior pulmonary vein; (D) right inferior pulmonary vein. The magnetic field vector is in yellow. The images displayed also show the magnetic catheter aligning parallel to the chosen magnetic field vector to reach each pulmonary vein. Fluoroscopic views (29° right or left anterior oblique projections including three catheter shadows) were previously stored still images. Real-time catheter location is displayed as the white-blue quadripolar catheter tip. Note: The red points on fluoroscopic images were desired locations transferred from CARTO RMT.
